Mauna Kea from Mauna Loa's upper Northeast Rift Zone

A view of Mauna Kea from Mauna Loa's upper Northeast Rift Zone. The haze in the saddle area, between Mauna Loa and Mauna Kea are caused by emissions from Kilauea Volcano. These emissions, known as Vog, are the result of volcanic gasses, primarily sulpher dioxide, mixing with moisture and dust in the atmosphere. Notice that the summits of both mountains are clear of haze, this is due to an inversion layer with an average height of about 6,000 feet, (2,000m). The result is a dry and stable atmosphere above the inversion layer. Photo: USGS
